Wiper blade for vehicle notifying of replacement timing

Abstract

A wiper blade having a plurality of check holes consecutively formed to pass through portions of a blade in contact with a windshield surface, allows a driver to clearly see a non-wiping portion on the windshield surface as the portions in contact with the windshield surface are worn out and the check holes are open and easily recognize a replacement timing. Mounting a conductive rubber band or a tensile force sensor on the portions of the blade, allows to easily detect a degree of the wear of a blade and, particularly, by changing conductivity or a tensile force as the check holes are open, allows to more easily check the replacement timing. Visually or audibly notifying the driver of the replacement timing according to a detected signal related to the replacement timing, allows the driver to perform safe driving in quick response to the detected signal.

What is claimed is: 
     
         1 . A wiper blade for a vehicle notifying of a replacement timing, which is installed on a wiper device of the vehicle, the wiper blade comprising check holes consecutively formed in a longitudinal direction to pass through portions in contact with a windshield. 
     
     
         2 . The wiper blade of  claim 1 , wherein a conductive rubber band or a tensile force sensor and a warning device are mounted on the wiper blade, and
 when the wiper blade is worn out and the check holes are open, the wiper blade issues warning through the warning device based on a signal detected by the conductive rubber band or the tensile force sensor.   
     
     
         3 . The wiper blade of  claim 2 , wherein the warning device is at least one of a horn which allows a driver to hear a sound and a warning lamp which allows the driver to visually check.
